FIELD OF THE INVENTION

The present invention relates to electrical power distribution systems and more particularly to a modular system for readily installing apparatus that provides for the distribution of power throughout the interior of a building in a pre-configured manner.

BACKGROUND OF THE INVENTION

Installing electrical power lines and wiring within buildings, particularly within large buildings, normally requires a custom/different configuration in the field for each locale and installation of a multitude of custom made conduits, railings, overhead struts, wiring and cabling, assemblies for supporting electrical components, tubing, circuit splitting and electrically powered device interconnections. Pre-existing electrical power distribution components have been devised for expediting the installation of electrical power throughout buildings. Devices such as switch assemblies, power panels, circuit breaker boxes, multi-circuit cabling and the like have been employed in the past in the set-up of large scale power distribution systems. The task of connecting a master or original source of power to the multitude of individual devices that are typically used within a building that require electrical power remains a labor intensive task of routing and connecting individual wires or collections of wires along extensive distances that are disposed along overhead, underground or floor level locations.

DETAILED DESCRIPTION

FIG. 1 shows one example of a power distribution system 10 according to the invention installed in a retail store environment 20. The retail store environment 20 as shown includes a series of adjacently disposed checkout stations 5, each station having multiple electrical power driven devices such as a cash register 15, a monitor 25, a storage device 27, a bar code scanner 29 and an electrical power delivery outlet 124 to which one or more other electrically powered devices 33 are connected via conventional plug-in to the outlet 124. As shown, the source of electrical power for all such devices originates from an external source that is connected to the system 10 via wiring 41 which is connected to and carrying the external source of power. The live master feed or source of electrical current wiring 41 from an external source is routed to the interior of the building, typically to a separate enclosed room 43 that is isolated from the remainder of the building. The master feed wire is typically routed into a housing 39 that is mounted on an interior wall, support or mounting structure 37. The housing 39 is mounted at a height level above the floor level surface 35 that is readily accessible by hand so that a maintenance or operational person is readily able to access a series of circuit breakers or fuses that are typically connected to a splitter mechanism for splitting the main circuit feed 41 within the housing or circuit breaker box 39. The housing 39 is typically provided with a small door 38 that a person or user of the system 10 can readily manually access and open when standing on the floor 35 to expose the interior of the housing 39 and gain access to a plurality of circuit breakers or fuses 51, FIG. 4. The primary feed 41 of electrical power and the split circuits typically have/contain relatively high electrical power/voltage relative to the amount/degree of power/voltage that is used for carrying out general building electrical requirements and typically 500 to 1,000,000 times the amount of current/amperage and/or voltage that is used in conventional systems for processing, generating, storing or transmitting digital data signals, bits, bytes or other units of digital electronic data. The primary power feed 41 typically ranges from about 20 to about 3000 amperes or from about 42 up to about 600 volts at 50/60 hertz and the individual circuits 51 into which the primary feed 43 is split typically range in current draw from a minimum of about 5, typically about 20 to about 400 amperes of about a minimum of 42 up to about 600 volts at 50/60 hertz. Such range of current and voltage typically exists along the entirety of the physical mediums along which the circuits extend from the fuse/breakers 51 to the electrical devices which are powered by the system 10, including along, through and within the materials of which the receptacles and pins of the various modular connectors described below are comprised.

As shown in FIG. 4, where alternating current (AC) is concerned, the main original power circuit feed cable 43 works in conjunction with a master neutral cable 45 and a master ground cable 47. The master live feed circuit 43 is split in a conventional manner (not shown) such as via a pole and associated wiring connected to the pole into a multiplicity of separate circuits that are each individually connected to and controlled by a plurality of circuit breakers or fuses 51 that limit the maximum amount of voltage and/or current that any particular split circuit can carry. As shown in FIG. 4 the system 10 includes a master circuit breaker or fuse 53 that limits the voltage/current flow through the entire split current system, each split circuit running in parallel to each other. Each one of the plurality of circuit breakers 51 and, as shown in the FIG. 4 embodiment, the ground wire/cable 47, are individually conductively connected via a plurality of individual conductive wires 57, 59, 61 to individual ones of a plurality of electrically conductive receptacles 63, 65, 67 that collectively serve to comprise a first modular connector 70 as detailed in FIG. 6.

The conductive receptacles 63, 65, 67 are typically configured in the form of a cup, bowl or other recess-containing receptacle of conductive material. Or, one or more of the receptacles 92 (or 107 as described below) can comprise strips of conductive material mounted on the interior surface of a cup or receptacle shaped structure as shown in FIGS. 5 & 6. The conductive receptacles 63, 65, 67 are mounted/disposed within the matrix of an electrically non-conductive support material 69 which typically comprises a unitary body in which the outer surfaces of the receptacles are completely embedded or surrounded by the non-conductive material 69 such that a user of the system is unable to easily to make manual contact, or is mechanically/physically prevented from making contact, with any surface, inside or outside, of the receptacles 63, 65, 67 which are carrying live electrical current once conductively connected to the main original source 41 of electrical power. The conductive material of which the receptacles 63, 65, 67 are comprised is physically connected to the conductive material of the wires/cables 57, 59, 61 by conventional means such as soldering or by uniform formation of the wire material together with the receptacle structure out of the same body of conductive material.

As shown in FIGS. 4, 5, 6, the body of non-conductive material 69 in which the receptacles 63, 65, 67 (92 generally) of the first connector 70 are embedded is mounted via screws 56 to the wall 40 of the housing 39 within or above an aperture provided in the wall 40 such that the recesses of the receptacles 63, 65, 67 are accessible from the exterior of the housing 39 to enable ready manual insertion of pins or projections 88, 89, 91 of a second complementary male connector 90. As shown in the FIGS. 4, 5, 6 embodiment, the first modular connector 70 includes a collar 80 surrounding the non-conductive material body 69. The collar 80 is configured so as to form a recess for receipt of a complementarily shaped portion 82 of the second connector 90. The collar 80 further serves to physically/mechanically obstruct or deter manual access to or engagement with the interior of the receptacles 63, 65, 67 for safety purposes

In the embodiment shown in FIG. 5, the second modular connector 90 has a plurality of pins 94 comprising individual pins of different sizes having different cross-sectional diameters and lengths 88, 89, 91. The arrangement of and the sizes of the plurality of pins 94 are selected to be complementary to the arrangement of and the individual sizes, i.e. depth, diameter, width, etc. of the plurality of receptacles 92 of the first connector 70 such that the plurality of projections or pins 94 can only be inserted into the recesses of the plurality of receptacles 92 in a single pre-selected orientation as shown in FIG. 6. In other words the connector 70 and 90 are keyed to each other such that they can only be connected as shown in FIG. 6 in a single unique orientation such that another modular connector cannot be mated with either of the two unless such another modular connector is identical in arrangement and size of either pins or receptacles. Although the embodiment shown in FIG. 5, shows pins of differing sizes, e.g. 91 and 94, the sizes of the plurality of pins and/or receptacles can all be selected to be the same or uniform. It is the arrangement of the mounting of the pins/projections and of the receptacles that is preferably selected to be unique (and complementary) in order to provide the keying or uniqueness of complementary arrangement of one connector to another for safety purposes. Each individual one of the pins 94 is comprised of an electrically conductive material, typically the same material as the material of which the receptacles are comprised which is typically a highly conductive metal material such as copper, nickel, iron, gold or the like alloys of one or more of such metals. In a preferred embodiment, the receptacles 92 have recesses that are shaped/sized so as to receive a corresponding one of the pins 94 in a manner that results in a snug fit engagement of the outside surfaces of the pins 94 with the outside surfaces of the recesses of the receptacles 92 such that a firm conductive engagement of metal surface on metal surface is formed when the pins 94 are fully inserted within receptacles 92.

As shown in FIG. 5, preferably, the depth D of the collar 80 is at least as large as or larger than the length L of the longest one 88 of the plurality of pins 94 so that none of the pins 94 can make physical conductive contact with one of the receptacles 92 and become electrically live until the full length of each/all of the pins 94 is fully housed or surrounded by the portion of collar 80 that extends above the top surface of the mounting block 69 in which the receptacles 92 are mounted/embedded. In this manner, the user cannot ever make manual contact with an electrically live metal pin 94. Because the receptacles 92 are fully surrounded by the electrically non-conductive substrate 69, it is difficult if not impossible for a user to make physical, manual contact with a live metal surface of one of the receptacles, the collar 80 further serving to deter/prevent such manual contact.

As shown in FIGS. 4, 5 each individual one of the pins/projections 94 of the connector 90 are separately conductively connected to one end of an electrically conductive wire, cable or the like 87. Each individual one of the wires 87 thus carries and corresponds to an individual one of the plurality of circuits that are split and formed within the housing 39. As shown, the collection of wires 87 are housed within and extend throughout the full length of a flexible tubular housing 86, FIGS. 1-5. In the embodiment shown in FIGS. 1, 2, 4, the distal end of the individual wires/cables 87 are routed out of the distal end of the flexible tube 86 directly through an aperture in a second housing 110 that acts as a distribution center for housing and organizing the distribution of the individual circuits to an electrically powered device. As shown in FIGS. 1, 4, the distribution housing 110 is typically mounted overhead within a large building out ready manual reach/access by persons standing on the floor level surface 35. As shown in FIGS. 1, 4, the plurality of wires can be routed within the distribution housing 110 to multiple electrical conductive connectors 112-122. One or more of the connectors 112-122 can be conductively connected directly to an electrically powered device or they can be connected to another multiple circuit electrical distribution outlet such as outlet 124 for connection to multiple devices 33 at any one or more stations where multiple electrically powered devices are located. As shown, the overhead housing 110 acts as a center of electrical circuit distribution and organization that simplifies the organization of the distribution of circuits for the user of the building space and its electrically powered devices. Each of the connectors 112-122 can be interconnected locally at a nearby station 5 or at a remote station 5 a via further routing of individual circuits through wires housed in and extending remotely via extended tubes, e.g. tube 6, FIG. 1.

In a most preferred embodiment, the distal ends of the plurality of wires 87 extending through tubular housing 86 are first routed to a third modular connector 100. The third modular connector comprises a plurality of receptacles 107 that are mounted/embedded within a non-conductive material 99 in a manner similar to the mounting and arrangement of receptacles 92 within material 69 of the first modular connector 70. The distal ends of the wires 87 are conductively interconnected to the receptacles 107 in the same manner as wires 57, 59, 61 were described as being conductively connected to receptacles 63, 65, 67. In the same manner as described with reference to connector 90, housing 110 is provided with a male connector 190 having a plurality of pins/projections for snug-fittable insertion within the recesses of receptacles 107. The male connector 190 has a body portion 191 that is complementary in geometry to the recess formed by collar 180 such that the body portion 191 can be readily manually inserted within the recess formed by collar 180 in the same manner as body portion or surface 82 of connector 90 is readily insertable into the recess of depth D created by collar 80. Again, because the receptacles 107 are live, once the connectors 70, 90 are connected, the distal modular connector 100 is preferably provided with a collar 180 that has a depth that is at least as large as or larger than the length of the longest one of the plurality of pins 194 so that none of the pins 194 can make physical conductive contact with one of the receptacles 107 and become electrically live until the full length of each/all of the pins 194 is fully housed or surrounded by the portion of collar 180 that extends above the top surface of the mounting block 99 in which the receptacles 107 are mounted/embedded. As shown in FIG. 5 and similar to the design described with reference to connector 70, the plurality of receptacles 107 of connector 100 can comprise individual receptacles 101, 103, 105 that are different in size and shape that are complementary to individual pins of the plurality of pins 192 for purposes of creating a safety uniqueness that requires mating in a unique orientation and that prevents the mating of differently configured connectors with each other. In any event the specific arrangement of mounting of the pins/projections 194 and the receptacles 107 are preselected such that the pins and receptacles only mate in a unique or keyed orientation.

The size, mass or other configuration of all of the receptacles and projections 92, 94, 107, 194 of all of the connectors 70, 90, 100, 190 are selected to enable a current transfer between correspondingly mated receptacles and projections that is 500 to 1,000,000 times the amount of current/amperage and/or voltage that is typically used in conventional systems for processing, generating, storing or transmitting digital data signals, bits, bytes or other units of digital electronic data. Each of the first, second, third and fourth connectors have a minimum of 5 separate high power or voltage circuit carrying contacts and typically a minimum of 8 and most preferably a minimum of 10.

In applications where alternating current are employed, both the first 70/second 90 and third 100/fourth 190 connectors preferably have a single projection and corresponding single receptacle that are interconnected to and serve as the master neutral wire/cable 45 for all of the plurality of circuits that are split/contained within the circuit splitter box 39 and carried/distributed via each connector. Similarly in such AC applications, both the first 70/second 90 and third 100/fourth 190 connectors typically have another single projection and corresponding receptacle that are interconnected to and serve as the master ground wire/cable 47 for all of the circuits that are split/contained within the circuit splitter box 39.

As shown in FIGS. 3, 5, 6, each of the connectors 70, 90, 100, 190 are configured and adapted to be unitary in structure devices that contain, house and support multiple separate conductive contacts each of which is separately capable of carrying and conducting a circuit of relatively high current or voltage. Each connector 90, 100 that is mounted on an end of the flexible tubular housing is readily manually connectable to a corresponding connector 70, 190.

As shown in FIG. 4, for example, the remote distribution outlet 124 may be interconnected to the appropriate wires contained within the primary overhead distribution housing via a flexible cable 111 having further connectors 113, 115 at either end of the cable 111 that interconnect respectively to a complementary connector 120 mounted on the overhead distribution housing 110 and to a complementary connector 117 of a cable 119 that connects directly to outlet 124. In the same manner, an electrically powered device such as a lighting fixture 300, 302, 304, FIG. 1 (connected via outlet connector 122 and flexible cable 310) or video monitor 200, FIG. 2 (connected via connector 120 and flexible cable 202), can be interconnected directly to one of the connectors of distribution housing 110 via the use of appropriate conductive cabling and connectors directly between the device and one or more of the connectors 112-122.

As shown in FIG. 1, the distribution housing 110 is typically mounted overhead on a mounting platform 320 beyond ready manual access from floor level. Conductive electrical connections to stations 5 a, 5 are effected via cables mounted along the length of the platform 320 connected at one end to the distribution housing via one or more of the connectors 112-122. The central electrical power room 43 containing the circuit splitter housing 39 is typically disposed/located anywhere between about 25 and about 2000 feet away from the remote stations 5 a, 5, lights 300, 302, 304 or other devices or outlets to which the split circuits within box 39 are ultimately interconnected. The length L1, FIGS. 2, 3, of the cable 86 and its associated plurality of wires 87 thus typically ranges between about 25 and about 2000 feet, more typically between about 25 about 300 feet in length. The length L2 of the cable or wire interconnection between the distribution housing 110 and an electrically powered device or a distribution outlet, e.g. cable 6, 310 or 311, FIGS. 1, 2, 3, typically ranges between about 10 and about 100 feet. Thus the preconfigured standardized design of the cable 86 and its associated modular components 70, 90, 100, 190 of the system 10 enables the relatively easy installation of cabling downstream of distribution housing 110 such as via cables 6, 111, 310, 311, FIGS. 1-3. The preconfigured standardized system 10 provides all of the electrical power necessary in preconfigured circuits along preconfigured arrangements of wires 87 to power any area within the interior 20 of the building without the necessity of having to separately construct and devise a pattern and housing for a multiplicity of split circuits 51 from the source 41 that must then, once split, be separately interconnected by individual wires over long distances to individual devices or outlets located at remote stations 5 a, 5.

The use in the system 10 of a pair of unitary, preconfigured connectors, 70, 90 that are keyed to each other and that each contain a plurality of high current/voltage carrying contacts enables the basic source of external electrical power 41 to be routed and distributed within/throughout the interior 20 without installation, matching or interconnection of individual cables or wires between the source 41 and the interior 20 of the building. The further inclusion of a second pair of unitary, preconfigured connectors, 100, 190 at the distal end of wires 87 that are keyed to each other and that each contain a plurality of high current/voltage carrying contacts further reduces the need for custom or labor intensive installation of individual cables or wires between the source 41 and the interior 20 of the building.
